Sewing Machiaes NOT QUITE SO DECISIVR AS IT WAS BUT A LITTLE MORE OVERWHELMING. WE CHALLENGE the representative of the Singer Sewing Machine Company, or any of the jurors on Sewing Machines at the Exhibition who voted for the report coming from that body to controvert the following statement of facts. Messrs Meddings, Cunnington, Dale, and Kirk, we call upon you to defend your report. H. C. FISKE & CO. Christchurch International Exhibition, June 15th, 1882. REPORT OF COMMITTEE OF EXPERTS. To H. C. Fiskb and Co. DEAR SIT?., — In accordance with jour request wo have examined the New Davis and tlie New Singer Machines for the purpose of comparing them.. In our comparison we have taken into consideration — 1. The mechanical principle involved. 2. The quality of the material uecd. 3. The degree of workmanship exhibited. 4. Tbe facility for doing a good and varied . class of work. After taking bcth machines asunder, care- ' fully_«xau_ining every piece, and fully testing their capabilities, we havo no hesitation in saying that we consider the Davis far the superior machine of the two. Our reasons are as follows : — In both machines the same method is adopted for actuating the needle bar, viz., a crank with roller working in a cam. This cam in the Davis Machine iB cut out of a solid piece of steel and hardened, while in tho Singer it is not only very much lighter, but is made of common cast iron. The feed apparatus of the two machines are very dissimilar. That of the Singer is the usual slip feed. The Davis has the vertical feed peculiar to itself. In this arrangement the pressor foot holds the material firmly down till the needle has reached its lowest point. Tho pressure is then relieved and transmitted to the feed bar. Feed bar, needle, and material are then, by a very simple contrivance, moved forward simultaneously the required length of stitch. Motion is given to tho shuttle in tho Davis machine as follows. An eccentric at the wheel end of the main spindle gives motion to a vertical lever, This in turn transmits it through a ball joint of ingenious construction to the only moving part under the machine, a pivotted lever having at its end an adjustable shuttle carrier. In the Singer Machine a pair of mitre wheels drive a verticle spindle, having at its lower end a crank. A connecting rod from this crank moves a sliding shuttle , carrier. It will be seen that in tlie Davis there are between the main Bpindle and the shuttle four points of friction, the pivot carrying the vertical lever, tho eccentric, the ball joint, and the pivot of horizontal lever. The two principal movements, the eccentric and ball joint, are adjustable, and the parts moat liable to wear are made of hardened steel. To compass the same work the Singer employs as points of friction the teeth of the mitre wheels, the two journals of vertical spindle, the two ends of the connecting rod, and the sliding shuttle carrier. None of these places are adjustable. The small wheels aro common cast iron, having a certain amount of backlusk, and consequent tendency to rattle and break. Tho connecting rod is a thin bar of iron, with a hole in each end. The end which runs on the crank pin is one of the principle joints in tho machine, having a considerable amount of work to do with small bearing surface, making it very liable to wear, while as before remarked, there are no means of compensating for any wear. It will be noticed that the shuttle of the Singer Machine is carried in a slide, to which a lateral strain is given by the driving rod causing a certain amount of friction, while in the Davis it is carried by the lever quite free from friction. With the exception of the small roller working the needle bar, there is not a single piece in the Binger Machine, not even excepting the shuttle, that cannot be cut with an ordinary pocket-knife, and there are no means of ad j usting any wearing part. In the Davis not only are most of pieces are made of steel, and tempered, but at every essential point means are provided for taking up any wear. On this point we may say that whero we had any doubt about the quality of the material employed the piece was broken and the fracture carefully examined. Having examined the mechanical arrangements of the two machines, we tested their adaptability for work, and we noticed the very peculiar feed of the Davis. In this respect we have been forced to the conclusion that for all purposes, sewing from the thinnest muslin to even through a metal spoon, the Davis has no parallel for grasp, or for avoiding that puckering often the effect of the pressure on a fore motion feed. We mnst in common honesty express our astonishment at the range and variety of work accomplished by the Davis, which we are satisfied cannot be done by the Singer. In summarising our report wo repeat that we have no hesitation in saying that we regard the Davis as very superior to the Singer in workmanship, material, and the mechanical principles involved, and also in performing a greater range of work. We found the Davis to work with equal ease from the lightest to the heaviest fabric. JOHN LEE SCOTT (Scott Bros.), Mechanical Engineer. T. GLUYAS PASOOE, Manager ef the Kaiapoi Clothing Factory. GEO.

RUDDOCK AND FRYER, The Sole Agents for Napier for the undermentioned now celebrated Machines, being able to confidently recommend them as tht best now before the public, hope to b< favored with a call from intending pur' chasers and others interested, feeling sur< that an examination must lead eventually tc the selection of the Light Running Standard CHE LIGHT RUNNING "STANDARD' .8 now to this market. It merits, however [ Ate such as to warrant the nope of its sooi becoming widely known, in fact a householc word in the town. These Machines combini ' simplicity, durability, speed, strength, beautj > and have reached the highest points of per fection ; have no equal, and will last a lift 1 time. Almost noiseless, easiest operated, an. above all the lightest running. Como anc judge for yourselves. THE HOME COMPANION (Hand). By tho same makers as the " Standard," is i perfectly reliable American-made Machine and has given unoquivocal satisfaction wher ever introduced, and deserves the atlentio. of the public. THE "STANDARD" KILTING MACHINE Will be found a great boon to Dressmaker and others, aud we anticipate a largo am ready sale for this. It can be worked b, hand, treadle, or steam power, and wil MAKE ANY KIND OF KlIjT DESIRED. Can b .- altered to different styles and widths imine diately, and in a niOßt simplo manner. All Machines may be purchased on th time payment principle. "OUDDOOK AND "piRYBI IRONMONGERS, NAPIER. 9
